Error install on Drupal 10

Did you try removing your composer.lock file?

Removing the composer.lock file seems to solve the first element in the problem, but the minimum-stability error persists:

% composer -W require 'drupal/term_merge:^2.0@beta'
./composer.json has been updated
Running composer update drupal/term_merge --with-all-dependencies
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - drupal/term_merge[2.0.0-beta1, ..., 2.0.0-beta6] require drupal/term_reference_change * -> found drupal/term_reference_change[dev-1.x, dev-2.x, 1.0.0-alpha1, 1.0.0-alpha2, 1.0.0-beta1, 1.x-dev (alias of dev-1.x), 2.0.0-beta2, 2.0.0-beta3, 2.x-dev (alias of dev-2.x)] but it does not match your minimum-stability.
    - Root composer.json requires drupal/term_merge ^2.0@beta -> satisfiable by drupal/term_merge[2.0.0-beta1, ..., 2.0.0-beta6].

Installation failed, reverting ./composer.json to its original content.

Maybe post your composer.json file?

Hello Guys,
here is my configuration for Drupal
https://prnt.sc/ur0o_B716ET9

I have installed this module using command
- composer require 'drupal/term_merge:^2.0@beta'
And I was able to download it without any error as you acn see in my aatached screenshot.

Please let me know where this error persists?

Hi @drupalnesia,

I have resolved the Drupal 10 installation issue and attached a patch.
Kindly review and verify. Thanks!.

You need to change your root composer.json "minimum-stability" to "beta" in order to install this module.
